HOLDER FOR LOOSE LEAF BINDERS Filed Oct. 1. 1927 Inventor Rebel-i J. Cope/an (J Patented Aug; 23, 1932 PATENT OFFICE ROBERr'LOOP AND, or TORONTO, ONTARIO, CANADA HOLDER}, F R LOOSE-LEAF BINDERS Application fil ed o cto ber 1, 1927. seriaino. 223,434.

The principal objects of the invention are to Overcome the difiic-ultiesand' inconvenienoes m t with in the handling of loose leaf binders,.particu1ar1yin machine posting, and to facilitate the handling of jbinders of the L shift type-in which the sections of the binder backers manipnl'atedto alterthe relationship oi'the'prong on'ti e different sections. further important object-is to pr videif) a means for supporting the book so that the leaves will lie out-perfeotlyflat, no matter what portion of the book is" being used and which also" will afford means for an arm restin-making entries on the lower end'oi the i6 Pages? T V v The principal feature of the invention consists in providing a supporting member for the binder covers and leaves having a recessed h .4 portion adapted to receive the seotions of th hinged binder back and further, to provide a-"po itive guidingelenient i said; recess to efieot'the desired positioning of' the binder backs: A Q In the drawin Figure. 1 isa; perspective '25 view ofa Iooseieaf binder shown supported by my improved device. Iiigure 2 is an e larged perspective detail of the binder'baok and the central supporting portion ofthe holder. W f 1 Figure 3 is a pers ecti e view similar to Figure 2 showing the shift binder baek moved in shifting the prongs. v r V v Figure 4 isan end elevation'alvie'w on a reduoed scale showing the position of the binder back and support with the binder prongs separated p Figure 5 is a perspective view of the holder showing one of th arm supports extended, Loose leaf binders, as at pres nt {3011; strnoted, are formed with metalbinderba'cks whiohare hinged centrally of theiriwidth and are adapted' toswiiig open to separate theprongs so that the loose sh ets i be removed and rep1a ed',"bnt whenthe leaves are to be tnrned I over the prongs have to be moved to overlapping position. These conditions require a considerable amount of manipulation andthe books; very-heavy, consequently" much inconvenience is experi;-

enced. Further, when the hinge back is locked with the prongs overlapping the pages will not lie flatr 7 Also in the type of binder known as a fs'hift binder it is very difl'icult to hold the sheets at one side whilea shift is beingmade and the sheets frequently slip off. the prongs causing great inconvenience and loss oftim'e.

The present invention has been devised to overcome the above recited objections and to further 7 assist in" the handling of the book and it comprises a holder 'on' which the book ei ,o

1 The holder as here shown is formed of a stiff board 1 which maybe of metal, fibre, Wood or heavy card havinga pair of ribs 2 6 arranged at the ends and a pair of ribs3farranged adjacent to the centre. The ribs 3 are preferably bevelled on their inner sides and a rib' 4, preferably bevelled on both sides is arranged centrally between the ribs The ribs 2 and 3 are preferably formed with-longitudinal grooves 5 in their inner and outer sides-respectively and boards 6 having edge ribs 7 are slidably supported in the grooves; I i

The top su'rfacesof the boards 6 are preferably arranged flush 'with'thetopsof the ribs and the spaces 8 beneath the sliding boards form convenient pockets for holding spare sheets for the books used thereon.

The holder thus described is placed upon a desk-and the,binder 8 is placed thereon as shown in Figure 1. The hinged back is unlocked and the hinge sections rest in the parallel bevelled grooves formed between the centre rib 4 and the adjacent ribs 3', as illustrated in Figures 1 and 2. When the binder is thus placed. the points 9 of' the binder prongs 10 are not separated so that the sheets I ll -may be removed but the'binder covers 12 Q0 and the sheets 11 rest perfectly flat so that entries may be made with the greatest ease. The sliding-boards 6' may be drawn out,

as shown; to form arm rests. It will be readily seen that as the points of the binder prongs are not separated to allow the sheets to come ofi such sheets may be'turned as effecti'vely asif the binder back were locked.

. If it be desired to remove sheets fromthe binder for machine positing or ther reasons When binders of the shift type are used.

the book is laid upon the holder and the back is unlocked and the sections then drop into the central grooves with the prongs overlapping, as shown in Figure 2 of the drawing,

the centre rib 4 acting .to break the hinge joint. The sheets may be turned as desired and when a shiftis desired it is merely neces-' sary to slip either half of thebinder, with the sheets arranged thereon, lengthwise of the grooves. vThis can be accomplished with the greatest freedom and both hands can be used in making the shift without the operator having to support or hold the hinder or sheets and there will be no possibilityof the sheets slipping off the prongs andbecoming pied. I have shown a very simple form of construction of holder but it must be understood that the construction may be varied considerably so long. as the holder is provided with a recess to allow the hinged back toopen and swing below the plane of the-underside of the covers. p

What I claim as my invention is: r Y '1. *A holder for loose leaf binders of the curved prong; type having a pair of hinged back sections hinged to thecovers, comprising a flat board, transverse ribs arranged at the ends of said board, and a pair of transverse ribs arranged adjacent to the centre and forming a central transverse channel recess to receive and position the hinge sections of the binder back, the upper surfaces ofall of said ribs being arranged in a common plane and forming rests adapted to engage and support thecovers of the binder in a common plane.

2; A holder for loose leaf binders of the curved prong type having-a pair of hinged back sections hinged to'the covers, comprising a flat board, transverse ribs arranged at the ends ofsaid board, and a pair of transverse ribs arranged adjacent to the centre and being bevelled on their opposing sides to form a centraltransverse channel recess of angular cross section to receive and position the hinge sections ofthe binder back, all of said ribs having upper flat surfaces arranged in a common plane to engage and support the covers of the binder in a common plane.

' V 3. A holder for loose leaf binders of the curved: prong type having a ,pair of hinged back sections hinged to the covers, comprising substantially horizontal supports for the binder covers adapted to support the covers each in a substantially horizontal position to facilitate entries, said supports being sepa- 35 rated'by a recess, the walls of saidrecess be= binderback.

ing adapted to co-operatively engage and position the hinged sections in a predetermined angular relation relative to'the h0rizontally supported covers to effect the positioningof the opposing sets of prongs with their ends overlapping, said supports engaging the covers ontheir outward sides in an extended manner to support theweight of the covers and sheets independent of the back members whereby the latter will be freely suspended within said recess for free manipulation therein.

4. A holder for loose leaf binders of the curved prong type having a pair of hinged back sections hinged to the covers,comprising a rigid; member having a pair oflflat surfaces disposed in a commonplane ladapt-l ed to support the covers, in-theiropen posi-j tion and a, recess extendingcentrally thererfl' across to allow the/hinged back sections to, 3 be depressed below the'lefvel of the binder covI-j ers, the walls of said recessbeing ada-pted to; engage and position said hinged back sections; to, support the prongs thereof in predetermined relation, said supports engaging the covers on their outward sides in anie xtended manner to support the weight ofitheocovers and sheets independentof the backmembers whereby the latter will be freelysuspended within said recess for free manipulation therein] 1 f 5.
